The  Most  Modern  and  Efficient  Concrete  Block 
Manufacturing  Plant  in  the  World 

EEIE^  ING  that  “Experience  is  the  Best  Teacher”,  The  Zagelmeyer 
Cast  Stone  Block  Machinery  Company  not  only  manufactures  the 
multiple  molds  for  casting  concrete  products  and  all  equipment  for 
the  production  of  granite  veneered  concrete  building  blocks,  hut 

_ _ J  also  operates  the  three  largest  and  most  modern  block  plants  in  the 

world  at  Bay  City,  Mich.;  Detroit,  Mich.,  and  Cleveland. 

0.  We  therefore  cannot  help  hut  feel  qualified  to  guide 
and  assist  others  desiring  to  follow  our  methods. 

In  all  three  of  our  large  cast  stone  block  plants  we  arc 
manufacturing  the  highest  quality  concrete  blocks  ever 
produced  at  the  lowest  cost  the  industry  has  ever  known, 
thereby  demonstrating  to  all  concrete  block  manufac¬ 
turers,  and  the  entire  building  industry  as  well,  that 
The  Zagelmeyer  System  is  a  thoroughly  proven,  success¬ 
ful  and  practical  method  of  producing  both  plain  and 
granite  veneered  concrete  blocks  in  large  quantities  at  a 
cost  so  low  that  a  market  of  almost  unlimited  possibili¬ 
ties  has  been  opened  up. 


Home  of  The  Zagelmeyer  System,  Bay  City,  Michigan 
A  model  of  efficiency  and  economical  methods  which  may  well  be  followed 
by  all  block  manufacturers  desiring  to  increase  profits  through  the  use  of 
practical  time  and  labor-saving  equipment,  efficient  plant  arrangement  and 
resultant  lower  production  costs.

Our  Detroit  plant  has  never  had  an  idle  working  day  since  it  teas  started  in 
1912  and  now  has  capacity  for  the  largest  production  of  any  concrete  block 
plant  in  the  world.  This  wonderful  growth  and  success  has  been  entirely  due 
to  the  high  quality  of  concrete  blocks  produced  and  demonstrates  the  oppor¬ 
tunities  open  to  all  block  manufacturers  adopting  the  Zagelmeyer  System 
methods  and  equipment. 


The  Zagelmeyer  System 

HE  process  of  manufacturing  absolutely  waterproof,  hollow,  concrete 
building  blocks  by  pouring  slush  concrete  into  patented  multiple 
molds  mounted  on  roller  hearing  trucks:  combined  with  the  method 
of  applying  a  sparkling,  pure  granite  veneer  facing  in  the  one  mold¬ 
ing  operation,  constitutes  The  Zagelmeyer  System — a  process  which  has  com¬ 
pletely  revolutionized  the  concrete  block  industry,  developed  a  new  and  popu¬ 
lar  building  material  to  a  practical  standard  of  production  and  is  fast  eliminat¬ 
ing  the  old  objectionable  dry-tamp  method  from  existence. 

\\  bile  the  Zagelmeyer  System  is  basically  a  process  or  method  of  manufactur¬ 
ing  plain  and  granite-faced  concrete  blocks  from  slush  concrete  and  casting 
them  in  multiple  molds,  it  also  includes  much  patented  equipment  for  the  most 
efficient  and  economical  production  of  this  popular  building  material. 

Every  detail  of  The  Zagelmeyer  equipment  is  so  thoroughly  protected  by  pat¬ 
ents  that  no  other  practical  method  of  manufacturing  granite-faced  concrete 
blocks  is  possible  without  infringement,  and  the  production  of  poured  concrete 
blocks  (either  with  or  without  the  granite  facing  process)  is  economically  im¬ 
possible  by  any  other  method  without  conflicting  with  the  Zagelmeyer  patents. 
Therefore  The  Zagelmeyer  System  affords  positive  and  complete  protection  to 
all  block  makers  securing  Zagelmeyer  Multiple  Molds  and  equipment,  through 
the  granting  of  territorial  manufacturing  process  rights  which  enables  you  to 
enter  a  profitable  business  without  fear  of  competition;  enables  vou  to  turn  out  a 
much  better  block  than  is  possible  by  any  other  method  and  at  a  much  lower 
manufacturing  cost:  and  furnishes  you  with  a  monopoly  legalized  by  the  t  .  S. 
patent  office  for  the  life  of  the  patents.

'l  ou  Can  Start  on  a  Small  Scale — Grow  Bin 

lou  can  obtain  the  exclusive  right  to  manufacture  these  blocks  in  your  terri¬ 
tory — we  give  you  absolute  protection  against  competition — and  you  can  build 
up  a  business  without  fear  of  cut  prices  putting  an  end  to  your  enterprise. 
Only  in  The  Zagelmeyer  System  will  you  find  a  guarantee  like  this. 

Competition  in  the  cement  block  industry  where  operations  were  conducted 
along  unprotected  methods  has  resulted  in  the  failure  of  many  a  business  con¬ 
cern  that  could  not  withstand  the  pressure  of  ‘"the  underbidding  mania”.  The 
Zagelmeyer  System  gives  you  an  assured  business  that  no  one  can  destroy — 
your  profits  are  sure  and  are  governed  only  by  the  volume  of  production  and 
capacity  ol  your  equipment. 

All  purchasers  of  Zagelmeyer  moulds  can  obtain  equal  protection  in  their 
respective  territory — regardless  of  whether  they  start  with  limited  equipment 
or  operate  on  a  large  scale. 

If  you  are  now  engaged  in  the  cement  block  business  you  know  the  defects  of 
the  dry  tamp  and  other  methods  ol  making  hollow  cement  building  blocks — 
you  also  know  that  anybody  can  make  cement  blocks  by  the  old  process,  and 
you  can  readily  appreciate  the  advantages  of  a  cement  block  manufacturing 
business  that  has  no  competition. 


Zagelmeyer  System  a  Proven  Success 

Since  1907,  when  I  he  Zagehnever  System  of  Multiple  Molds,  granite  veneering 
process  and  equipment  were  finally  perfected,  steady  progress  has  been  made, 
until  today  concrete  block  manufacturers  in  every  state  in  the  union  are  suc¬ 
cessfully  using  this  equipment  and  building  up  strong,  substantial,  non-com¬ 
petitive  businesses  that  are  in  every  case  showing  great  earning  capacities. 
There  are  many  Zagelmeyer  System  concrete  block  plants  throughout  the  coun¬ 
try  with  large  capacities  and  making  handsome  profits. 

Vi  herever  you  find  a  Zagelmeyer  System  Concrete  Block  Concern  you  will  note 
that  it  is  enjoying  a  practical  monopoly  of  the  concrete  block  business  in  that 
community,  is  experiencing  a  steady  growth  and  expansion  year  after  year,  and 
paying  substantial  returns  on  the  investment. 

In  some  localities  there  are  still  to  be  found  a  few  small  concerns  or  individuals 
struggling  along  in  a  feeble  sort  of  make-shift  way  with  the  old  “dry-tamp 
system  and  laboriously  turning  out  inferior  blocks,  one  at  a  time,  by  hand. 
Such  competition,  however,  amounts  to  but  little  and  is  fast  being  eliminated.

Other  Processes  Cannot  Compete 

The  modern  time  and  labor-saving  methods  of  The  Zagelmeyer  System  has 
reduced  the  cost  of  production  to  a  point  where  blocks  made  by  any  other 
process  cannot  possibly  compete  either  in  price  or  quality. 

There  is  no  question  whatever  as  to  the  permanency  of  the  steadily  increasing 
demand  for  granite-faced  blocks  made  by  The  Zagelmeyer  process.  The  beauti¬ 
ful  appearance,  great  strength,  durability,  waterproof  qualities  and  low  cost 
have  won  favor  throughout  the  entire  building  field.  The  remarkable  growth 
of  the  plants  using  Zagelmeyer  System  molds  and  equipment  is  proof  sufficient 
that  The  Zagelmeyer  System  has  solved  the  concrete  block  problem,  overcome 
all  of  the  defects  of  blocks  made  by  other  processes  and  beyond  a  doubt  placed 
the  granite-faced  concrete  block  among  the  foremost  of  high-grade  standard 
building  materials.

A  glance  at  the  above  photographic  reproduction  of  a  small  section  of  a  Zagel- 
meyer  granite  veneered  smooth-faced  concrete  block  shows  the  perfection 
of  our  process.  The  grains  of  granite  which  make  up  the  facing  lie  so  close 
together  that  no  cement  can  be  seen.  The  outer  surface  is  entirely  free  from 
cement  and  nothing  but  the  i>ure,  sparkling  granite  crystals  show,  while  the 
backs  of  these  crystals  are  permanently  imbedded  in  neat  cement,  holding 
them  securely  against  the  ruvages  of  time  and  weather. 


This  twenty-four  inch  Zagelmeyer  granite  veneered  smooth-faced  concrete 
block  is  not  a  special  sample,  but  a  block  taken  from  regular  stock.  It  has 
not  been  treated  with  acid,  nor  sprayed  nor  scrubbed,  but  is  just  as  it  came 
from  the  mold.  These  sparkling,  beautiful  blocks  can  be  made  either  rock 
or  smooth-faced  for  less  money  than  the  ordinary  sand-faced  block  by  the 
dry-tamp  process.  No  concrete  blocks  were  ever  made  by  any  method  that 
equals  them  for  appearance,  quality,  strength,  or  imperviousness  to  heat, 

cold  or  moisture.

Note  that  our  rock-faced  design  has  every 
appearance  of  having  been  rough-hewn  with 
mallet  and  chisel  from  a  block  of  solid 
granite.  The  block  shown  is  our  standard 
16-inch  size  with  two  dead  air  cells.  These 
dead  air  cells  act  as  a  non-conductor  to  heat 
and  cold,  thus  thoroughly  insulating  a  build¬ 
ing  and  idso  make  possible  a  lighter  and 
more  easily  handled  block. 


Granite  Faced  Concrete  Building  Blocks

UJ} 

YER  since  concrete  blocks  were  first  conceived,  manufacturers  have 
continually  experimented  with  various  methods  of  facing  the  bloeks 
in  an  attractive  and  practical  manner.  Numerous  facings  have 
been  attempted,  but  tbe  difficulty  lias  always  been  to  apply  tbe 
a  practical  manufacturing  method  at  a  cost  that  was  not  prohibitive, 
is  it  universally  recognized  that  The  Zagelmeyer  System  makes  it 


facing  by 
Not  only 

possible  to  manufacture  a  perfect  concrete  block,  but  also  that  the  process  of 
applying  a  pure,  sparkling  granite  facing  is  a  crowning  feature  that  distinguishes 
this  product  as  the  last  word  in  concrete  blocks. 


They  are  low  in  first  eost  as  compared  with  other  high-grade  building  materials, 
cost  less  to  lay — making  a  rapid  and  economical  construction  possible  and  re¬ 
quire  no  upkeep  for  repairs  or  paint. 


The  16-inch  and  24-inch  lengths  in  both  smooth  and  rock  iace  as  shown  on  this 
and  opposite  page  have  been  generally  adopted  as  standard  lengths  of  blocks 
meeting  all  building  requirements.  In  addition  to  our  standard  size  cores  we 
are  prepared  to  furnish  cores  any  special  size  to  conform  with  varying  building 
codes  in  different  territories. 

Molds  are  also  furnished  as  desired  for  the  manufacture  of  angle  blocks,  corner 
blocks,  one-balf  blocks,  one-quarter  and  three-quarter  blocks.  Thus  all  difficult 
construction  problems  are  ideally  met  with  this  extremely  versatile  building 
material. 


These  granite  faces  are  not  only  beautiful  when  new  but,  unlike  all  other  con¬ 
crete  blocks,  retain  their  sparkling  beauty  indefinitely.  All  other  blocks 
become  badly  discolored  within  a  few  months  because  they  are  so  porous  that 
the  rain  carries  the  dust  and  dirt  into  the  blocks.  Our  blocks  are  free  from 
pores  and  are  absolutely  waterproof,  so  that  the  rain  tvashes  the  dust  off 
and  therefore  they  always  hold  their  original  sparkle  and  lustre.

The  upper  picture  shows  the  method  of  treating  the  face  plates  before  applying 
the  granite  facing.  The  center  illustration  shows  how  the  slush  concrete  is 
poured  into  the  multiple  molds,  directly  from  the  big  automatic  mixer.  The 
lower  illustration  shows  the  molds  having  the  cores  inserted 
just  before  being  filled. 

Page  Ten 


Illustration  shows  how  artificial  heat  is  applied  to  facilitate  the  drying:  so  that 
all  the  molds  are  used  once  each  day.  This  view  shows  but  one  side  of  a  i>or- 
lion  of  the  tunnels  at  our  own  plant  in  Bay  City.  The  tunnels  are  a  duplicate 
on  the  opposite  side,  allowing  room  for  two  cars  end  to  end 
in  each  tunnel  opening. 

How  Zagelmeyer  System  Granite  Faced  Concrete 

Blocks  are  Made 

N  producing  GRANITE  VENEER  concrete  blocks,  a  face  plate  is 
first  coated  with  a  thin  specially  prepared  glue,  then  covered  with 
crushed  granite  particles.  By  turning  the  plate  over,  all  the  surplus 
particles  which  do  not  adhere  to  the  face  plate  drop  off,  after  which 
late  is  set  away  until  the  glue  hardens,  which  takes  about  one  hour. 

Just  before  putting  the  face  plates  in  the  multiple  molds,  the  granite  crystals 
that  now  form  a  complete  coating  on  the  face  plate,  and  held  firmly  in  place 
by  the  hardened  glue,  are  given  a  coating  of  pure  cement  mixed  with  water  to 
the  consistency  of  a  thin  paste.  This  coating  of  “neat”  cement  is  applied  with 
a  brush,  and  the  purpose  of  this  coating  is  to  imbed  the  crystals  in  a  layer  of 
pure  cement.  The  face  plates  are  now  ready  to  he  inserted  in  the  molds. 

The  next  step  is  to  fill  the  multiple  molds  with  slush  concrete  and  leave  the 
mixture  to  harden.  As  the  wet  concrete  mixture  is  poured  directly  against  the 
cement  coated  side  of  the  face  plate,  the  two  surfaces  “set”  together  so  that  the 
granite  veneer  facing  becomes  a  part  of  the  block  itself.  While  the  mixture  is 
“setting”  the  water  from  the  wet  concrete  softens  the  glue  which  holds  the 
granite  crystals  to  the  face  plate,  so  that  when  the  blocks  are  removed  from 
the  molds  they  appear  just  as  you  see  them  in  the  illustrations,  requiring  no 
further  treatment  whatever. 

The  only  purpose  of  the  glue  is  to  hold  the  granite  crystals  in  place  and  to  pro¬ 
tect  one  side  of  them  from  cement  while  the  block  is  being  cast.  THIS  GLUE 
ALL  COMES  AWAY  WITH  THE  FACE  PLATES  IN  GRANULAR  FORM. 

and  three  or  four  strokes  with  a  wire  brush  cleans  the  face  plates  for  the  next 
coating  of  glue. 

Feeble  attempts  have  been  made  to  produce  granite  and  other  natural  stone 
laces  by  using  acid  to  eat  away  the  cement.  Attempts  have  also  been  made  to 
obtain  the  desired  results  by  spraying  before  the  cement  has  set.  These  meth¬ 
ods,  however,  are  expensive  and  impractical  and  the  results  have  never  been 
satisfactory.

1  lie  Zagelmeyer  System  is  the  only  successful  and  practical  process  ever  con¬ 
ceived  for  applying  a  beautiful  granite  veneer  facing  on  concrete  blocks,  and 
our  method  is  so  simple  and  so  inexpensive  that  it  adds  but  very  little  to  the 
cost  of  the  blocks. 

The  Zagelmeyer  "Wet  Mix’*  Process  Insures  an  Absolutely 

Waterproof  Block 

It  has  been  known  for  some  time  by  all  practical  concrete  engineers  that  con¬ 
crete  building  blocks  made  by  the  so-called  “wet-mix”  system  arc  about  twice 
as  strong  as  blocks  made  by  the  now  obsolete  “dry-tamp”  system.  Concrete 
blocks  made  of  slush  concrete  overcome  that  greatest  of  all  objections  to  drv- 
tamp  blocks— their  porousness.  No  matter  how  carefully  made  or  how  well 
tamped,  dry-tamp  blocks  are  full  of  pores  and  absorb  moisture  freely.  On  the  * 


While  the  manufacture  of  Cast  Concrete  Building  Blocks  on  the 
Zagelmeyer  System  is  a  very  profitable  business  when  con¬ 
ducted  on  a  large  scale  in  a  large  city,  it  is  also  a  very  attrac¬ 
tive  business  for  the  man  of  limited  means  in  a  small  town  or 
village.  We  very  often  have  customers  start  in  a  small  or 
medium-sized  village  with  only  two  or  three  sets  of  molds  and 
by  adding  a  few  molds  each  year  develop  a  very  substantial 
business. 


other  hand,  blocks  made  by  the  wet-mix  process — that  is,  if  the  concrete  is 
mixed  wet  enough  so  that  it  can  he  poured  directly  into  the  mold  and  allowed 
to  remain  there  undisturbed  while  the  initial  set  is  taking  place — require  no 
tamping,  every  atom  of  cement  is  completely  crystallized  and  the  result  is  a 
perfectly  dense  block,  free  from  all  pores  and  CONSEQUENTLY  ABSO- 
LL  TEL\  Vi  ATERPROOF  and  a  block  of  the  greatest  possible  strength. 

It  is  density  (freedom  from  pores)  which  makes  a  waterproof  block.  And  it 
is  necessary  to  use  plenty  of  water  to  make  the  mass  liquid  enough  to  insure 
perfect  precipitation  so  that  the  pores  will  he  completely  closed  through  com¬ 
plete  crystallization,  t  nder  the  Zagelmeyer  System  the  concrete  mix  is  suffi¬ 
ciently  thin  to  (low  freely  to  all  parts  of  the  mold  without  tamping. 

The  excess  moisture  can  he  driven  off  as  rapidly  as  required,  and  it  makes  abso¬ 
lutely  no  difference  to  the  quality  of  the  block  whether  this  is  done  in  an  hour 
or  a  week.  The  length  of  time  required  for  the  “set”  to  take  place  and  the 
blocks  to  harden  sufficiently  to  permit  removal  depends  entirely  upon  the  tem¬ 
perature  of  the  air.  As  the  heat  necessary  to  drive  off  the  moisture  sets  the 
cement  quicker  than  it  evaporates  the  moisture,  by  the  time  one-half  of  the 
moisture  has  left  the  block  the  block  is  hard  enough  to  take  out  of  the  molds 
and  yet  still  retains  enough  water  to  supply  the  cement  with  the  necessary 
moisture  to  insure  proper  curing.  The  blocks  are  so  dense  that  they  will  retain 
some  of  this  moisture  for  days,  even  if  the  block  is  set  out  in  the  hot  sun,  and 
for  this  reason  blocks  made  by  our  system  require  no  sprinkling  after  being 
taken  from  the  molds.

Molds  Used  Once  a  Day 

At  ordinary  summer  temperature,  with  I  airly  quick  setting  cement,  the  blocks 
can  he  removed  in  from  twenty  to  twenty-four  hours,  so  that  in  summer  weather 
the  molds  can  be  used  once  per  day  without  artificial  heat.  By  applying  arti¬ 
ficial  heat  and  keeping  them  in  a  temperature  of  120  degree  F.  for  eight  or  ten 
hours,  they  can  he  removed  in  twenty  hours,  and  the  molds  can  he  used  once 
each  day  in  any  kind  of  weather.  The  best  method  of  applying  artificial  heat 
to  the  molds  is  with  a  series  of  small  tunnels,  heated  with  steam  pipes,  each 
tunnel  just  large  enough  to  admit  a  car  of  molds;  the  number  of  tunnels,  of 
course,  depending  upon  the  capacity  required.  Tunnels  of  wooden  construction 
can  he  used,  hut  it  is  better  to  build  them  of  concrete  and  the  cost  is  not  much 
greater. 

A  few  tunnels  can  be  built  and  a  few  cars  of  molds  purchased  to  start  with,  and 
more  cars  can  he  added  as  desired.  The  price  at  which  these  blocks  sell  for 
over  all  other  makes  will  soon  give  you  money  to  buy  more  cars.  Every  cus¬ 
tomer  is  a  satisfied  one  and  brings  you  another,  and  in  this  way  your  trade 
increases  and  soon  develops  into  a  permanent  and  profitable  business. 

How  to  Obtain  Granite  Crystals  and  Glue 

There  are  several  reliable  sources  of  supply  which  we  can  recommend  to  all 
block  manufacturers  adopting  I  he  Zagelmeyer  System. 

In  order  to  establish  a  universal  standard  of  appearance  of  Zagelmeyer  Granite 
Veneered  Concrete  Blocks  it  is  desirable  in  so  far  as  possible  to  maintain  cer¬ 
tain  sources  of  supply,  and  we  have  arranged  to  carry  large  stocks  on  hand  out 
of  which  we  can  fill  less  than  car  load  orders  sent  to  us  direct.  We  recommend 
where  car  load  lots  are  wanted  that  orders  be  placed  direct  with  the  quarries. 
Granite  Crystals  are  packed  in  sacks  containing  100  lbs.  We  can  make  ship¬ 
ments  from  our  Bay  City  plant  in  all  quantities  on  short  notice. 

We  also  carry  in  stock  considerable  quantities  of  the  special  glue  used  in  apply¬ 
ing  the  granite  crystals  to  the  face  plates  and  can  make  prompt  shipments  at 
all  times.

Granite  Faced  Cast  Stone  Block  Houses  Have 
Many  Advantages  Over  Other  Types 

ROGRESS  in  concrete  block  constructions  for  dwellings  lias  taken 
rapid  strides  within  the  past  few  years  as  the  many  advantages  of 
this  tvpe  of  building  becomes  more  generally  understood. 

There  is  no  doubt  hut  that  the  sparkling  beauty  of  the  granite  crys¬ 
tals  comprising  the  facing  of  Zagelmeyer  Cast  Stone  blocks,  enhanced  by  the 
natural  rock  surface  design,  adds  attractiveness  and  distinctiveness  to  homes  built 
of  this  material,  and  the  originality  of  architectural  designs  possible  is  prac¬ 
tically  unlimited. 

Chief  among  the  primary  reasons  why  concrete  block  dwellings  have  many 
advantages  over  other  types  are  greater  permanency,  greater  warmth  in  winter 
and  greater  coolness  in  summer,  greater  economy,  lower  upkeep  and  the  fact 
that  houses  of  this  type  are  fireproof. 

Granite-faced  concrete  blocks  cost  less  than  almost  any  other  high-grade  building 
material  and  cost  considerably  less  for  laying,  as  they  require  less  labor  than 
brick  or  wood  construction.  More  rapid  construction  is  possible  with  concrete 
blocks  than  with  any  other  known  material.  As  Zagelmeyer  granite-faced 
blocks  never  lose  their  sparkling  beauty  and  require  no  upkeep  or  repairs 
the  economies  and  advantages  of  this  type  of  construction  is  becoming  more 
generally  realized. 


There  is  a  snugness  and  warmth  about  homes  built  of  Zagelmeyer  Granite¬ 
faced  concrete  blocks  that  appeals  to  the  desire  for  cozy  appearance  and 
substantial  construction.

The  Perfect  Material  for  Porches  and 

A 

Foundations 


HE  widespread  popularity  of  Zagelmeyer  Granite-faced  Concrete 
Blocks  for  foundations  and  porches  is  due  entirely  to  their  supe¬ 
riority  over  all  other  building  material  for  such  construction 
requirements. 

In  the  hrst  place,  two  big  economies  are  made  possible.  Zagelmeyer  concrete 
blocks  cost  less  than  any  other  material  suitable  for  basement  construction, 
and  cost  far  less  to  lay,  the  savings  on  material  and  labor  invariably  averaging 
from  33  1/3  to  50  per  cent. 

Another  very  important  advantage  of  Zagelmeyer  concrete  blocks  is  the  fact 
that  they  are  absolutely  waterproof  and  the  hollow  wall  construction,  because 
of  the  dead  air  spaces  in  the  blocks,  makes  a  positively  dry  basement  that  is 
cool  in  summer  and  warm  in  winter,  these  dead  air  spaces  acting  as  a  non¬ 
conductor  to  heat  or  cold.  Zagelmeyer  concrete  blocks  are  so  perfectly  dense 
and  free  from  pores  that  no  moisture  of  any  kind  can  possibly  he  absorbed, 
even  if  the  block  is  laid  in  water.  Never,  under  any  circumstances,  will  there 
he  found  any  moisture  or  mold  on  the  inside  of  the  basement  wall  if  built  of  this 
material. 

Owing  to  the  light  gray  color  of  Zagelmeyer  concrete  blocks,  the  interior  of 
basement  is  materially  brightened,  presenting  an  extremely  light,  clean  surface. 
Being  built  of  poured  slush  concrete,  Zagelmeyer  cast  stone  blocks  have  the 
same  strength  as  though  a  wall  were  built  of  solid  concrete,  thus  making  the 
strongest  possible  construction.  Foundations  for  the  tallest  skyscrapers  are 
made  of  slush  concrete  poured  into  molds,  following  the  same  identical  prin¬ 
ciple  by  which  Zagelmeyer  blocks  are  made.

The  popularity  of  stucco  construction  for  fine  homes  opens  a  wide  field  for  the 
Zagelmeyer  cast  stone  block  manufacturer,  as  there  is  no  better  base  for 
stucco  exteriors  than  waterproof,  hollow  concrete  blocks.

Za&elmeyer  Cast  Stone  Blocks  make  the  Best 
Construction  for  Stucco  Work 


HERE  is  .absolutely  no  better  base  possible  for  higli-grade  stucco 
work  than  waterproof,  bollow  concrete  blocks  made  by  The  Zagel- 
ineyer  System. 

On  account  of  the  fact  that  the  expansion  and  contraction  of  stucco 
is  identically  the  same  as  that  of  concrete  blocks,  cracking  of  the  walls  I  a  com¬ 
mon  objection  to  stucco  work  when  laid  over  metal  or  any  other  base)  is  abso¬ 
lutely  prevented. 

A  stucco  house,  with  the  stucco  laid  over  Zagelmeyer  System  concrete  blocks, 
is  warmer  in  winter,  cooler  in  summer,  easier  to  beat  and  makes  the  strongest 
possible  construction  In  addition  this  type  of  construction  is  positively  fire¬ 
proof,  a  feature  of  considerable  importance  in  large  cities  wher  the  building 
codes  are  rigidly  observed  on  this  question. 

Zagelmeyer  System  concrete  blocks  cost  no  more  than  metal  lath  and  are  far 
superior,  owing  to  the  greater  strength  of  block  construction  and  the  fact  that 
the  dead  air  space  due  to  the  hollow  cells  of  the  concrete  blocks  lias  many 
advantages  over  any  other  base  for  this  purpose,  thoroughly  insulating  the 
building  against  beat  and  cold. 


Some  of  the  finest  stucco  homes  in  the  country  are  constructed  with  stucco 
laid  over  Zagelmeyer  System  concrete  blocks.

No  material  is  better  adapted  for  fireproof  garage  construction  than  granite-faced  concrete  blocks.

Fireproof  Qualities  of  Zagelmeyer  Cast  Stone  Blocks  Open 
Big  Field  in  Building  Modern  Garages 

HERE  are  two  essential  requirements  in  selecting  a  building  mate¬ 
rial  for  garage  construction — strength  and  fireproof  qualities. 
Zagelmeyer  granite  veneered  concrete  blocks  ideally  meet  both 
of  these  requirements. 

Aside  from  solid  stone  or  steel  reinforced  concrete,  no  possible  building  mate¬ 
rial  could  offer  equal  strength  to  Zagelmeyer  cast  stone  blocks,  and  no  other 
material  of  equivalent  strength  presents  such  possibilities  for  beautiful  appear¬ 
ance. 

It  requires  a  strong  wall  to  support  a  strong  and  heavy  floor  and  all  garages 
must  have  strong  floors  and  fireproof  walls.  It  is  on  this  account  that  builders 
of  garages  immediately  recognized  tbe  advantages  of  Zagelmeyer  granite 
veneered  hollow  concrete  blocks  for  this  purpose.  Thousands  of  modern  garages 
are  now  being  constructed  of  this  material  in  all  parts  of  the  country. 


fT  hetlier  a  mammoth  public  garage  or  a  small  private  garage,  Zagelmeyer 
granite-faced  concrete  blocks  meet  the  exacting  requirements  for  such  types 
of  construction  as  are  slioun  in  the  above  pictures  and  also 
on  the  opposite  page.

Railroads  are  Adopting  Cast  Stone  Block 
Construction  for  Economy  and  Permanency 


AILROADS  are  fast  replacing  wooden  buildings  with  a  more  perm¬ 
anent  type  of  construction.  Depots,  round  houses,  freight  sheds, 
signal  towers,  and  other  railroad  buildings  arc  subjected  to  a  con¬ 
siderable  fire  hazard,  and  it  is  now  becoming  widely  recognized 
lroad  officials  that  permanent,  fireproof  buildings  are  by  far  the 
most  economical  and  best  suited  to  their  requirements. 

Then,  too,  economy  in  first  cost  and  economy  in  upkeep  is  a  big  consideration 
for  railroad  building  construction  work. 


among  rai 


Zagelmeyer  System  granite-faced  concrete  blocks  are  by  far  the  best  suited  for 
such  exacting  purposes  and  fully  meet  all  of  the  requirements  of  railroads 
such  as  fireproof  construction,  economy,  permanency,  elimination  of  upkeep 
and  maintenance  cost,  and  better  appearance.  In  connection  with  the  better 
appearance  of  granite-faced  blocks  for  railroad  use,  many  railroads  have  found 
that  buildings  constructed  of  this  material  are  easily  kept  clean  and  free  from 
smoke,  dust  and  soot  by  flushing  occasionally  with  a  stream  of  water.  The 
smooth  granite  surface  of  these  blocks  will  not  retain  the  dirt  and  are  easily 
flushed  spotlessly  clean  w  ith  hose  and  water.  This  is  particularly  desirable  for 
depots  and  signal  towers.

Zagelmeyer  Cast  Stone  Blocks  are  Suitable  lor  Widely 
Diversified  Types  of  Fine  Buildings 


OSPITALS,  schools,  factory  buildings,  stores  and  large  public  build¬ 
ings  are  being  built  of  granite-faced  concrete  blocks  because  of  the 
strength,  permanency,  fireproof  qualities,  economy  and  beautiful 
appearance  of  Zagelmeyer  granite-faced  concrete  blocks. 

In  fact,  there  is  hardly  a  building  purpose  for  which  these  blocks  do  not  possess 
superior  advantages  over  all  other  materials. 

During  the  past  five  or  six  years  particularly  there  has  been  an  increasing  use 
of  Zagelmeyer  System  blocks  in  the  construction  of  large  buildings,  and  manu¬ 
facturers  of  our  blocks  throughout  the  country  are  finding  a  tremendous  field 
open  to  them  along  this  line. 

Contractors  have  been  favorably  impressed  with  these  blocks  because  of  the 
economy  and  ease  of  laying  and  the  great  saving  of  labor  possible  as  well  as 
the  rapidity  of  construction  where  the  time  element  must  be  considered. 

From  every  standpoint  it  can  be  readily  appreciated  that  a  steadily  increasing 
use  of  Zagelmeyer  blocks  for  fine  buildings  is  bound  to  bring  them  into  the 
front  rank  of  favored  materials  for  such  construction  purposes.

Farmers  and  dairymen  are  beginning  to  favor  Zagelmeyer  System  concrete 
blocks  as  the  ideal  type  of  construction  for  barns,  and  this  field  presents  golden 
opportunities  for  block  manufacturers. 

Page  Twenty-eight 


Farm  Buildings  of  Cast  Stone  are  Dry,  Warm,  Fireproof  and 
Will  Outlast  All  Other  Building  Materials 

ARMERS  all  desire  a  dry,  warm  and  fireproof  barn  to  house  their 
livestock,  grain  and  implements.  All  over  the  country  sentiment  is 
gradually  swinging  to  greater  permanency  for  farm  buildings. 

W1  terever  Zagelmeyer  concrete  blocks  have  been  introduced  into  a 
community  for  the  erection  of  line  farm  buildings,  others  have  quickly  fallen 
in  line  and  strongly  favored  this  material  on  account  of  its  very  apparent  supe¬ 
riority  for  general  building  purposes  on  the  farm. 

The  hollow,  insulated  walls  mean  warm  and  dry  interiors  in  winter  and  cool 
barns  and  stables  in  summer.  The  fireproof  qualities  of  concrete  block  con¬ 
struction  are  especially  essential  for  barns  and  country  buildings  on  account  of 
the  absence  of  fire  protection,  and  still  another  point  in  favor  of  concrete  blocks 
is  their  low  cost,  it  being  considerably  cheaper  when  everything  is  taken  into 
consideration,  than  most  other  kinds  of  material  suitable  for  such  purposes. 

Concrete  Block  barns  are  permanent  buildings,  will  not  need  replacement,  and 
require  no  painting  or  upkeep  expense.  Once  erected,  they  are  a  monument 
to  the  far-sighted  judgment,  pride  and  enterprise  of  the  man  who  builds  them.

The  Cast  Stone  System  of  Making  Concrete  Blocks 
vs.  the  Dry  Tamp  System 

HE  “drv-tamp"  system  of  making  cement  l)loeks  consists  of  making  all 
blocks  in  one  mold.  The  mixture  is  simply  dampened  and  is  tamped 
into  the  mold  and  removed  at  once.  With  the  Cast-Stone  or  Wet- 
Mix  System  the  mixture  is  made  very  wet  and  is  poured  into  the 
molds  without  tamping,  and  is  allowed  to  remain  there  until  the 
initial  set  of  the  cement  has  taken  place  and  the  block  is  hardened. 

Even  the  best  blocks  made  by  the  “dry  tamp'”  system  are  weak  and  so  porous 
and  soak  up  so  much  water  that  buildings  made  from  these  blocks  are  always 
damp  and  unhealthy.  \\  inter  rains,  followed  by  a  sharp  frost,  in  a  short  time 
are  apt  to  disintegrate  them,  and  the  structure  becomes  weak  and  dangerous. 

I  he  reason  is  plain  and  simple.  It  is  impossible  with  the  “dry-tamp”  system 
to  add  water  enough  to  the  mixture  to  crystallize  more  than  a  portion  of  the 
cement.  If  more  water  was  used,  the  blocks  would  fall  apart  when  removed 
from  the  mold,  which  has  to  he  done  at  once,  as  the  mold  is  used  over  and  over 
again. 

“Dry-tamp  ”  blocks,  after  being  made,  are  sometimes  put  into  steam  curing 
rooms  in  a  vain  endeavor  to  remedy  the  above  mentioned  evil.  This,  however, 
helps  hut  little,  as  it  only  ages  the  block  prematurely  and  cannot  possibly  fill 
the  voids  after  the  block  is  once  formed.  There  is  hut  one  way  in  which  this 
can  he  done,  and  that  is  by  adding  water  enough  to  the  mixture  to  crystallize 
all  the  cement,  which  at  the  same  time  makes  the  mass  plastic  enough  so  that 
the  voids  are  filled  by  precipitation,  and  in  order  to  do  this,  enough  molds 
must  he  provided  to  allow  the  cement  to  set  before  removing  the  blocks. 

The  Cast-Stone  or  Wet-Mix  System  of  block  making  consists  of  making  the  mix¬ 
ture  so  wet  that  every  atom  of  cement  is  crystallized,  and  then  so  thoroughly 
mixing  it  that  even'  particle  of  sand,  gravel  or  stone  of  which  the  aggregate 
consists,  is  perfectly  coated  with  cement.  This  creamy  mixture  is  then  poured 
directly  into  the  molds,  the  mixture  being  so  thin  that  it  flows  freely  to  all 
parts  of  the  mold  without  tamping.  The  mixture  is  allowed  to  remain  in  the 
molds  while  the  cement  takes  its  initial  set  undisturbed  and  the  block  hardens. 
The  result  of  this  cast  is  a  beautiful  block  resembling  natural  stone  so  closely 
that  it  is  difficult  to  tell  the  difference. 

As  there  are  some  who  think  dry  heat  is  injurious  to  concrete,  we  wish  to  state 
that  to  “dry  tamp”  concrete,  heat  is  certainly  very  injurious,  hut  to  concrete  as 
wet  as  we  use  it,  extended  experiments  have  proven  beyond  a  doubt  that  heat 
up  to  the  point  of  driving  off  the  excess  moisture,  does  not  affect  the  quality 
of  the  concrete  a  particle. 

In  a  mixture  wet  enough  to  make  a  good  cast,  such  as  is  used  in  our  process, 
all  the  water  is  used  that  the  cement  requires,  which  makes  the  concrete  liquid 
enough  so  the  particles  will  precipitate  and  close  the  pores,  thus  making  an 
absolutely  WATER-PROOF  BLOCK.  Complete  precipitation  takes  place  within 
a  few  moments  after  the  molds  are  fdled  and  the  excess  moisture  can  then  be 
driven  off  as  rapidly  as  required,  and  it  makes  no  difference  to  the  quality  of 
the  block  whether  this  is  done  in  an  hour  or  a  week. 

The  heat  necessary  to  drive  off  the  moisture  sets  the  cement  quicker  than  it 
evaporates  the  moisture,  so  that  by  the  time  one-half  of  the  moisture  has  left 
the  block,  the  block  is  hard  enough  to  take  out  of  the  molds  and  the  block  still 
retains  water  enough  to  supply  the  cement  with  the  necessary  moisture  to 
properly  cure  same.  The  block  is  so  dense  that  it  retains  some  of  this  moisture 
for  days,  even  if  the  block  is  set  out  in  the  hot  sun.  and,  for  this  reason,  blocks 
made  on  our  system  require  no  sprinkling  after  being  taken  from  the  molds.

Granite  Facing  Machine 

HIS  machine  is  for 
putting  the  granite 
crystals  on  the  face 
plates  after  the  face 
plate  has  been  given  a  coating 
of  glue,  it  is  locked  in  the  ma¬ 
chine  by  a  turn  of  a  small  hand 
wheel.  The  box  underneath  is 
divided  and  contains  two  sizes  of 
crystals.  A  small  hand  scoopful 
of  the  coarse  size  is  first  put  into 
the  box,  the  bottom  of  which  is 
the  face  plate;  then  the  large 
hand  wheel  is  turned  toward  the 
compartment  containing  the 
coarse  crystals,  until  the  box  is 
completely  upside  down,  and  at 
the  same  time  the  compartment 
moves  under  the  box  and  all  crystals  that  do  not  adhere  to  the  glued  surface 
of  the  face  plate  drop  back  into  the  compartment  from  which  they  came.  The 
box  is  then  brought  to  an  upright  position  and  the  fine  crystals  are  then  applied 
in  the  same  way.  Two  men,  with  this  machine,  clean  the  face  plates,  glue 
them  and  apply  the  crystals  at  the  rate  of  100  per  hour.  Where  only  a  few 
molds  are  operated,  it  is  not  necessary  to  have  one  of  these  machines,  as  we 
furnish  a  much  cheaper  outfit  for  small  plants,  but  for  200  or  more  molds,  this 
machine  soon  pays  for  itself. 


Adjustable  Angle  Block  Molds 


The  above  outfit  consists  of  an  adjustable  mold  for 
making  five  angle  blocks  at  a  time.  These  molds 
are  not  mounted  on  trucks  but  are  usually  placed 
at  some  convenient  place  where  they 
can  he  easily  filled  and  where  the 
blocks  will  not  have  to  he  carried  too 
far  when  removed.  The  blocks  to 
use  with  the  16-in.  size  is  12  in.  long 
on  one  end  and  4  in.  long  on  the  other 
end.  For  the  24-in.  size  they  are  12 
in.  long  on  one  end  and  6  in.  on  the 
other.  We  make  them  for  8,  10  or 
12-in.  walls,  with  either  plain  or  rock 
face  plates.

Become  a  Silo  Manufacturer  by  the  Zagelmeyer 

System 


I  L  O  S  built  with  cast 
blocks  made  by  the  Zagel¬ 
meyer  System  are  abso¬ 
lutely  air-tight  and  water¬ 
proof.  This  is  essential  in  silo  con¬ 
struction.  These  blocks  are  also  frost, 
wind  and  fireproof;  cannot  blow 
over;  never  need  repairs  or  attention; 
are  practically  indestructible  and 
make  a  permanently-built  silo;  are 
more  durable  than  any  other  kind  of 
construction  and  ARE  CHEAPEST 
TO  BUILD. 

Genuine  satisfaction  lias  been  express¬ 
ed  wherever  silos  have  been  con¬ 
structed  of  waterproof  blocks  made 
by  tbe  Zagelmeyer  System,  it  being 
the  universal  opinion  of  all  farmers 
who  have  purchased  Zagelmeyer  Sys¬ 
tem  Silos  that  they  represent  tbe  one 
type  of  construction  that  is  without 
a  fault  and  that  they  are  by  far  the 
cheapest  in  the  end. 


“Zagelmeyer  Silos  are  unequalled”,  says 
David  II  right,  whose  granite-faced  silo  kept 
his  silage  from  freezing  at  15  degrees 
below  zero. 


Nothing  in  the  concrete  industry  is  more  profitable 
than  furnishing  silo  blocks  to  progressive  and  pros¬ 
perous  farmers.

Cost  of  Manufacturing  Blocks  by  the  Zagelmeyer 

System 

WING  to  the  fact  that  the  cost  of  materials  varies  in  different  locali¬ 
ties  it  is  impossible  to  give  an  exact  cost  of  manufacturing  Zagel¬ 
meyer  System  blocks  which  would  be  universally  correct. 

It  is  easy  to  compute  the  cost  of  manufacturing  our  blocks  in  your 
own  locality  by  merely  filling  in  the  correct  material  prices  in  the  list  given 
below  and  inserting  your  local  prices  for  labor. 


The  following  table  shows  the  exact  amount  of  material  and  labor  required 
to  manufacture  one  thousand  8  x8  x24"  blocks  or  1500  8  x8  x!6  plain  blocks. 


25  bbls.  cement  @  .  $

Add  three  cents  extra  for  granite  facing  for  the  24”  block. 

Items  such  as  depreciation,  interest,  insurance,  and  other  general  overhead 
charges,  should  he  included  in  order  to  arrive  at  a  definite  estimate  of  maim- 
facturing  cost.  The  above  will,  however,  afford  a  good  basis  for  comparative 
costs  and  enable  you  to  readily  determine  the  economical  advantages  and  tre¬ 
mendous  savings  possible  through  the  use  of  modern  methods  and  equipment 
which  greatly  reduces  labor  costs.

Zagelmeyer  Multiple  Molds  for  Casting 
Concrete  Brick 

Makes  Concrete  Bricks  Cheaper  than  Clay  Bricks  and  Opens  New 
Possibilities  for  t lie  Concrete  Block  Manufacturer 


PROCESS  of  casting  concrete  bricks  in  multiple  molds,  400  at  a 
time,  and  making  possible  the  handling  of  the  cast  bricks  in  units 
of  10  at  a  time — a  process  so  simple  that  one  man  can  make  four 
thousand  bricks  a  day — has  been  perfected  by  us  as  a  further  expan¬ 
sion  of  The  Zagelmeyer  System. 

Experiments  have  been  conducted  for  nearly  ten  years  by  this  company  in  the 
effort  to  develop  a  practical  method  of  manufacturing  concrete  bricks  at  a  cost 
which  would  make  the  use  of  concrete  bricks  commercially  economical.  Two 
years  ago  Mr.  F  rank  Zagelmeyer,  president  of  the  Zagelmeyer  Companies,  per¬ 
fected  the  present  molds  and  began  the  manufacture  of  concrete  bricks  on  a 
commercial  scale  in  the  three  large  block  plants  operated  by  his  concern. 

It  was  conclusively  demonstrated  during  the  past  two  years  that  concrete 
bricks  could  be  manufactured  by  the  Zagelmeyer  System  at  a  cost  even  below 
that  of  making  common  clay  brick,  making  it  possible  to  offer  concrete  bricks 
to  the  building  field  in  direct  competition  with  all  other  kinds  of  brick. 

Page  Forty 


I  lie  saving  of  time  and  labor  is  the  principle  reason  why  it  is  possible  to  make 
concrete  bricks  under  the  Zagehneyer  System  cheaper  than  to  manufacture 
oilier  bricks  by  any  present  method.  Naturally  the  cost  of  the  materials  in  the 
manufacture  of  concrete  brick  is  considerably  higher  than  the  raw  material 
for  production  of  clay  brick  but  tbc  Zagehneyer  System  more  than  offsets  this 
in  a  reduction  of  labor  costs,  thereby  placing  concrete  bricks  in  an  advantageous 
position  so  far  as  trade  competition  is  concerned,  as  they  can  be  sold  for  less 
than  the  market  price  of  any  other  bricks  and  on  account  of  tliis  low  cost  can 
be  used  for  practically  all  purposes  for  which  building  bricks  are  used. 

Made  by  the  Same  Process  as  Zagehneyer  Concrete  Blocks 

The  Zagehneyer  System  of  Multiple  Brick  Molds  consists  of  forty  open  end 
units,  each  holding  ten  bricks,,  or  400  molds  in  all,  mounted  on  a  roller  hear¬ 
ing  truck.  The  molds  can  he  quickly  set  up  on  the  truck  and  the  truck  run 
under  a  concrete  mixing  machine  where  the  slush  concrete  is  poured  directly 
into  the  brick  molds.  The  truck  is  then  run  into  heating  tunnels  or  kilns,  heated 
with  steam  pipes,  and  allowed  to  remain  in  a  temperature  of  120  degrees  for 
eight  to  ten  hours  before  removal.  This  allows  the  concrete  to  take  its  initial 
set  before  removing  the  bricks  from  the  molds.  The  length  of  time  required 
for  the  set  to  take  place  and  the  bricks  to  harden  sufficiently  to  permit  removal, 
depends  upon  the  temperature  of  the  air.  At  ordinary  summer  temperature, 
without  the  heated  tunnels,  and  with  fairly  quick-setting  cement,  the  bricks  can 
be  removed  in  from  20  to  24  hours,  so  that  the  molds  can  be  used  once  each 
flay  in  any  event. 

After  the  concrete  has  taken  its  initial  set,  the  bricks  are  ready  for  removal 
and  final  curing.  The  only  handling  the  bricks  receive  during  the  entire  process 
of  manufacture  is  when  they  are  taken  from  the  molds,  and  this  is  simplified 


This  cut  illustrates  the  method  of  removing  the  brick  from  the  molds ,  which 
are  so  simple  to  operate  that  one  man  makes  four  thousand  brick  per  day. 

Page  Forty-one 


This  view  further  illustrates  the  brick  beiiift  removed  from  the  molds  and 
stacked  in  a  /tile.  By  this  process  brick  can  be  made  cheaper  than  by  any 
other  kn otvn  method  and  yet  the  quality  of  the  brick  produced  is  far  superior 
to  most  high-grade  and  high-priced  clay  brick. 


l»y  handling  ten  bricks  at  a  time  in  the  unit  of  ten  molds.  The  workman  lifts 
out  the  units  and  deposits  the  ten  bricks  on  a  pile  in  one  operation,  without 
handling  each  individual  brick. 

Bricks  are  Made  from  Slush  Concrete 

Owing  to  the  fact  that  the  bricks  are  made  from  slush  concrete,  a  mixture  is 
obtained  which  becomes  perfectly  dense  and  free  from  pores,  thereby  insuring  an 
absolutely  waterproof  brick  of  much  greater  crushing  strength  and  consider¬ 
ably  greater  hardness  than  most  other  types  of  brick. 

The  practicability  and  low  cost  of  manufacturing  concrete  brick  under  The 
Zagelmeyer  System  opens  up  tremendous  possibilities  in  an  almost  unlimited 
field  for  this  grade  of  new  building  material,  and  due  to  the  small  investment 
required  for  producing  bricks  under  this  system,  the  making  of  concrete 
bricks  is  possible  for  small  manufacturers,  building  supply  dealers,  and  even 
contractors  to  enter  this  field. 


To  the  man  of  limited  means  in  a  small  town  the  manufacture 
of  these  brick  is  unusually  attractive.  The  smaller  places  do 
not  usually  have  a  brick  factory,  and  as  brick  are  very  heavy 
transportation  adds  materially  to  the  original  cost,  and  this 
fact  enables  the  manufacturer  of  Cast  Concrete  Brick,  at  all 
points  where  there  are  no  brick  factories,  to  make  a  double 
profit. 


Page  Forty-two 


Referring  to  this  cut  you  will  note  there  are  ten  bricks  to  the  unit  and  each 
face  plate  holds  two  units.  The  molds  here  illustrated  are  to  cast  a  brick 
21A"x3%"x71/8"  and  the  set  has  the  following  specifications:  Diameter  of 
wheels,  10";  width  over  all,  48";  length  over  all,  8' 10" ;  weight,  1400  pounds; 
height  above  rail,  23";  standard  track  gauge,  24" ;  other  gauges  to  order. 


This  view  shows  a  four-hundred  mold  set  of  molds  mounted  on  an  all-iron 
roller  bearing  truck  before  being  filled.  Molds  can  be  furnished  for  any  size 
brick,  but  the  size  of  the  molds  cannot  be  changed,  after  they  are  made.

Small  Investment  Required 

A  few  tunnels  can  he  built  and  a  few  molds,  mounted  on  trucks,  can  he  pur¬ 
chased  to  start  with,  and  more  equipment  added  as  desired.  As  each  car,  or 
truck  of  molds,  has  a  capacity  for  casting  400  bricks  at  a  time,  and  as  each  car 
or  set  of  molds  can  he  used  once  daily,  any  desired  production  can  he  readily 
figured  in  terms  of  equipment  required.  Twenty-five  cars  of  molds  would  give 
a  plant  capacity  of  10,000  bricks  per  day. 

The  trucks  used  for  these  molds  are  about  the  same  size  and  of  the  same  track 
gauge  as  the  ones  used  for  Zagelmeyer  Multiple  Block  Molds,  and  the  many 
manufacturers  of  Zagelmeyer  Cast  Concrete  Block  can  manufacture  the  brick 
with  no  other  expense  for  equipment  that  the  actual  cost  of  the  molds. 

There  is  no  question  as  to  the  market  for  concrete  bricks.  Concrete  is  fast 
becoming  a  leading  building  material,  and  the  only  reason  concrete  brick  has 
never  been  used  extensively  is  on  account  of  the  previous  impracticability  of 
manufacturing  them  in  quantities  at  a  reasonable  cost.  With  the  method  of 
manufacture  brought  to  a  practical  basis,  and  the  cost  reduced  to  a  par  with 
that  of  clay  brick,  it  can  be  readily  appreciated  that  the  possibilities  for  use 
of  concrete  brick  are  almost  beyond  conception,  as  the  comparative  quality  of 
concrete  brick  and  common  brick  is  all  in  favor  of  the  stronger,  harder  and 
more  permanent  qualities  of  concrete. 

Material  Required  for  1000  Brick 

The  cost  of  manufacturing  concrete  brick  may  be  readily  computed  from  the 
following  information:  The  material  required  for  producing  one  thousand 
concrete  brick  under  The  Zagelmeyer  System  is  one  and  five-eighths  yards  of 
gravel  and  one  and  three-quarters  barrels  of  cement.  The  size  of  brick  covered 
by  this  material  requirement  is  the  size  which  we  have  adopted  as  standard — 
2^"x3:?4  x7”N  .  Any  desired  size  of  brick  can  be  made  by  our  system  by  having 
molds  made  to  order. 

As  the  cost  of  cement  and  gravel  varies  in  different  localities,  we  have  avoided 
giving  definite  cost  figures.  By  taking  the  prevailing  market  price  of  gravel  and 
cement  in  your  city  and  multiplying  it  by  the  quantities  of  material  required 
for  the  production  of  1,000  brick,  and  then  figure  that  one  man  can  make  4.000 
bricks  per  day,  you  will  find  that  the  cost  of  labor  and  materials  for  the  manu¬ 
facture  of  Zagelmeyer  System  Concrete  Brick  is  way  below  the  cost  of  making 
common  clav  brick.
